T3/T04e .63 AR 57 Trim N/R difference

[nb07bcar]

I have a th04-15G turbo right now on my ka. How much of a difference would I see by putting on this turbo T3/T04e .63 AR 57 Trim. right now I run 10-12 psi and I've looked at the efficincy on my 15G and i'm in the 60's. Whis this turbo I belive I would have greater efficency which means more power, but is it worth my money to upgrade?

that is a small turbo youre running. i wouldnt be boosting more than you are right now or else youll just be blowing hot air. youll see a major difference in switching to a t3/t4. itll be a totally different beast. you wont have nearly as quick of spool up as you do now, but if youre looking for more effecient power then itd be a wise idea to upgrade. you can go with a .48 ar for quicker spool, and itd still be a good turbo for more power. it all really depends on when and where you want that power. the .63 will def flow more up top but take just a tad bit longer for spool up. i myself have a t3 .63 ar/t4e 50 trim. havent used it yet though, but def be looking out for my posts to see how it goes. its your choice though, faster spool go with the .48, more top end go with the .63.
